Aberasi kromatis

The term aberasi kromatis derives from two Latin roots: aberratio (deviation, from the verb aberrare, meaning 'to wander from a path') and chromaticus, adapted from the Greek khroma (χρῶμα), meaning 'color'. The phenomenon was first scientifically identified by Isaac Newton in the 17th century, who observed that a single glass lens cannot focus all wavelengths of light at the same focal point. In modern photography and astronomy, this defect is corrected using achromat or apochromat lens designs that combine glass elements with different refractive indices. In Indonesian scientific literature, the term is used as the standard formal designation in optics, physics, and professional photography.
